The method of extraction of Ag by cyano complex formation followed by metal disp
The method of extraction of Ag by cyano complex formation followed by metal displacement is called
- A. Parke's method
- B. McArthur-Forest method
- C. serpeck method
- D. Hall's method
Step-by-step solution
The McArthur-Forest process is a cyanidation method used for extracting gold and silver. It involves forming a soluble cyano complex, e.g., [Ag(CN)2]-, followed by displacement of the metal using zinc. The other options refer to different processes: Parke's method for desilverization of lead, Serpeck's method for bauxite purification, and Hall's method for aluminum extraction.
